electrically connecting to a battery in the cell phone. The battery
connector 100 includes an insulating housing 2 and a plurality of
electrical terminals 3, wherein the insulating housing 2 is a
vertical housing and has a top mating wall 21, a front wall 22, a
rear wall 23, a plurality of vertical walls 24 arranged
alternatively on the top mating wall 21, and a plurality of
terminal receiving chambers 25 relatively formed between each of
pairs the vertical walls 24, the top mating wall 21 has a plurality
of openings 211 respectively communicating with the terminal
receiving chambers 25 for penetrating through the terminal
receiving chambers 25. Each pair of the vertical walls 24
sandwiching one of the terminal receiving chambers 25. A pair of
ledges 212 projects oppositely between the crossover sides of the
opening 211 and the vertical walls 24. Two opposite ends of each
opening 211 in the top mating face 21 defines a plurality of
stand-offs 213, or the stand-offs 213 can be set on the top mating
face 21 anywhere. Besides, the rear wall 23 of the insulating
housing 2 has a plurality of ribs 231 integrally backwardly
extending thereof and respectively corresponding to the vertical
walls 24, and a receiving groove 232 formed between the rear wall
23 and the ribs 231, and a plurality of limiting grooves 233 formed
in the crossover sides of the rear wall 23 and the ribs 231. The
two outermost vertical walls 24 thereof respectively expose
outwardly a clamping block 241 for orienting with a housing of the
electronic device while the battery connector 100 assemblies to the
electronic device.
Each of the electrical terminals 3 is respectively received in the
corresponding terminal receiving chambers 25. Each of the
electrical terminals 3 is a flexuous terminal and has a body 31, a
conducting portion 32, a resilient portion 33, and a contacting
portion 34 (please referring to the FIG. 4 at the same time),
wherein the body 31 is a rectangular sheet disposed longitudinally
and has a first side 311 and a second side 312 opposing to the
first side 311. The conducting portion 32 is formed by an extension
downwardly tilting extending from the first side 311 and in a hook
shape. The conducting portion 32 has a first portion 321 tilting
downwardly and a second portion 322 integrally extending from the
first portion 321, the first portion 321 and the second portion 322
cross to press a joint on a printed circuit board 7 (referring to
the FIG. 5). Besides, the body 31 has a plurality of teeth 313 at
the opposite edges for mounting in the limiting grooves 233 of the
housing.
The resilient portion 33 extends from the second side 312 of the
body 31 integrally and extends crookedly upwardly, the resilient
portion 33 formed a V-shaped and has a .LAMBDA.-shaped contacting
portion 34 integrally connecting to an end of the resilient portion
33, the contacting portion 34 has a first arm 341 and a second arm
342, the first arm 341 integrally upwardly extends from an end of
the resilient portion 33 first and then bent a sharp with a
generally ".LAMBDA." shape extends laterally integrally to form the
second arm 342. A pair of wings 343 defined at the free end of the
second arm 342 and controls the height of the contacting portion
34, which out of the opening 211. A contact point 344 is located
between the first arm 341 and the second arm 342, preferably at the
point of the generally ".LAMBDA." shape.
In assembly, the electrical terminals 3 respectively insert into
corresponding terminal receiving chambers 25. The terminal body 31
is located in the receiving grooves 232. After assembly, the body
31 of each of electrical terminals 3 is oriented in each of
receiving grooves 232 by suppressions with the plurality of
limiting grooves 233 and interferences with the plurality of teeth
313. The conducting portion 32 out of the receiving groove 232.
After assembling to the electronic device (No Shown), the
conducting portion 32 electrically connecting to the PCB 7 and
further the conducting portion 32 locates in the receiving groove
232, which has the ribs 231, to limit a displacement of the
conducting portion 32 and avoid the imperfect contact between the
conducting portion 32 and the PCB 7.
The contacting portion 34 out of the top mating wall 21 from the
terminal receiving chamber 25, a battery 8 aligns locations of the
electrical terminals 3 from a top of the battery connector 100 and
moves to a bottom thereof to suppress a corresponding terminals on
the contacting portion 34 while the battery connector 100
electrical connects the battery 8. Because of the corresponding
terminals retains the contacting portion 34 to the bottom thereof
to drive the resilient portion 33 constricting from a top to a
bottom in the terminal receiving chamber 25, and the resilient
portion 33 has a contacting resistance generating by the elastic
recovery to drive the contacting portion 34 moving upwards to
tightly the corresponding terminals to electrically connects the
battery connector 100 to the battery 8. During above-mentioned
process, the stand-offs 213 of the housing have an important
action, the height of the stand-offs 213 is lower than the portion
of the contacting portion 34 out of the top mating wall 21. With
this design, the stand-offs 213 can limit the downward movement of
the contacting portion 34 of the electrical terminals 3 and relieve
a pressing force to the contacting portion 34.
